Specification of Letters Patent.

Patented Jan. 5, 1915;.

Application filed December 9, 1913. Serial No. 805,597.

To all whom it may concern:

Be it known that I, FRANK W. OMAN, a citizen of the United States,residing at Spokane, in the county of Spokane and State of Washington,have invented a new and useful Water-Motor, of which the following is aspecification.

This invention relates to improvements in current water motors.

An object of the present invention is to provide a current motorhingedly secured to a float so that" it may be tilted or inclined to bein operable position within the water.

A further object is to provide a wheel with a bar extending at rightangles to the axis thereof and which is adj ustably secured at differentheights so that the inclination of the plane of rotation of the wheelmay be varied and regulated.

A further object is to provide a hingedly mounted wheel with a shaftextending substantially parallel to the hinge connection and which shaftis provided with a beveled gear engaged with a similarly beveled gearthe latter being secured to the wheel. This shaft is adjacent the hingedconnection so that the shaft will remain practically stationary forsmall adjustment in the inclination of the wheel.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the drawings accompanying this specification and forming a partthereof, the preferred embodiment of my invention is illus trated, inwhich Figure 1 is a vertical sectional view of my improved current motorand tilted at such angle as to be partially submerged in the water so asto be driven thereby. Fig. 2 is a top plan view of the foregoing.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 3 is a float and whichas illustrated in Fig. 1, is very low in the water so that the topsurface l thereof will approximate the level of the top surface of thewater. The float is adapted to move about in the water so that broadflat board 7 and to which is secured the rearwardly extending adjustingrod 8. The adjusting rod 8 is provided with the opening 9 extendingtherethrough at the rear end thereof and through which opening extendsthe post 10, the latter being pivotally secured to a base 11. The post10 is provided with a plurality of apertures 12 extending transverselytherethrough and which apertures are adapted to register with a similaraperture 13 extending transversely through the adjusting rod 8 andthrough which apertures when properly alined, extends a locking pin 14:,thus holding the board 7 rigidly in any required angular position.

Mounted upon and rigidly secured to the board 7 is the Vertical bearing15 which rotatably receives the axle 16 therein. The axle 1.6 isthreaded as at 17 and to which is secured the collar 18 whereby the axleis prevented from moving out of the hearing. A beveled gear 19 isrigidly secured to the axle 16, to which gear is connected the wheelspokes 20, the latter carrying at their outer extremities, the blades21. Thus the gear forms a hub as well as performing its usual functions.As an additional support for the spokes 20 and blades 21, the rods 22are provided rigidly secured to the spokes and blades and radiatingcentrally and secured to a disk 23, the latter being threadedly securedto the axle at some little distance above the gear 19. Thus the trussrods will strengthen the wheel and provide a rigid structure. Extendingbetween the blades are the tension members 24 whereby the various bladesare held spaced apart and materially strengthened. From the foregoing itwill be apparent that as the shelf or board 7 is tilted through theintervention of the adjusting rod 8 and post 10, the axle 16 will betilted a corresponding amount, bringing the blades at one side of thewheel into contact with the water and partially submerging the sametherein.

In order to transmit the power obtained from the wheel, the shaft 25 isprovided, which is mounted in suitable bearings 26 spaced at equalintervals along the shelf 7.

A beveled gear 27 is secured to one extremity of the shaft and mesheswith the beveled gear 19 from which it derives its power. The remote endof the shaft is provided with the sprocket wheel 28, around whichextends the chain 29. In this connection it is tobe noted that the shaft26 extends parallel to and adjacent the hinge 6 so that the movements ofthe sprocket wheel in common with the shaft 25 and shelf 7 will berelatively small for small adjustments in the angular position orobliquity of the Wheel. The slight shifting of the sprocket wheel istaken up by and allowed for by the chain 29. The wheel operatesaccording to the well known principle of subjecting the blades upon oneside of the axle to pressure in one direction and upon the other sidecausing the blades to move above and out of the water.

Having thus described my invention, what I claim is An apparatus of theclass described comprising a float, a shelf extending along and hingedlysecured to one edge thereof, means for locking said shelf in adjustedinclined positions, a vertical bearing carried by said shelf, an axlethreaded at its extremities and rotatably supported by said verticalbearing, a beveled gear rigidly secured to said axle preventing theshifting thereof in one direction, a plurality of spokes radiating fromand rigidly secured to said gear which acts in the capacity of a hubtherefor,

blades carried by said spokes, a horizontal shaft extending along androtatably mounted upon said shelf, a gear carried by said horizontalshaft and meshing with said beveled gear, means for transmitting powerfrom said horizontal shaft to mechanisms supported by said float, acollar mounted upon the lower threaded extremity of said axle preventingthe shifting thereof in a direction opposite to the limitation imposedby said beveled gear, and a disk thrcadedly i Copies of this patent maybe obtained for five centa each, by addressing the Commissioner ofPatente.
